• Make required error appears only the primary key generated in prior Database Table insert trigger

  Dear all,

  I am a beginner in the ADF and am under Jdeveloper Studio Edition Version 12.2.1.0.0.

  
  

  I'm trying to insert a record, I created the trigger for insertion prior to get the primary key and set some other default values.

  
  

  On the page, I did read-only primary key column and false required.

  
  

  When I try to save - commit (Programmatic), I get errors for the required value. How can I stop this errors.

  
  

  Secondly, I also tried changing the agent to disabled on the attribute View object that raised the error below:

  If the primary key values from DB sequence, you can follow this approach:

  Using the sequence of database in ADF - Souza Waslley Blog

  Oracle Fusion Middleware Technologies: ADF 11 G: generate the primary key sequence number

  Otherwise, instead of DB trigger, create the DB function that retrieves the value of the PK and call stored function in the overloaded method create() entity:

  11 GR 2 11.2.0.3 under linux

  Hi everyone,.

  It's an honor to be with you guys.

  I have a big question here and I am unable to decide on a permanent solution.

  We have a primary database that is configured to have a logical expectation.

  The logic of the day before was not built by me. But I'm now support...

  So as the title suggests, there is NO primary index / unique + not null on a large number of tables in the database of emergency primary/logic. But the application logic guarantees uniqueness values rather than null.

  Here is where the problem starts.

  Guys request DO NOT want us to create an index on the primary database.

  According to my understanding, because the database lack of clues, the apply SQL must do a full table scan whenever it changes / remove data. It is a very expensive process and consumes a lot of time. This takes hours together to apply a minute with a value of newspapers on the logic of the eve... A huge lag is created during the hours and is not acceptable.

  So as I told you earlier, the guys request do not want an index on the tables not supported.

  They use the database pending logic exclusively for information purposes and it's like production for them...

  
  Let me give an overview...

  According to the document on the creation of the logic of the day before for 11.2 as below

  http://docs.Oracle.com/CD/E11882_01/server.112/e41134/create_ls.htm#SBYDB4730

  Step 1 to find tables without identifying unique logic in the primary database.

  Query the DBA_LOGSTDBY_NOT_UNIQUE view to display a list of tables SQL may not apply be able to uniquely identify. For example:

  SQL> SELECT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_NOT_UNIQUE

   2> WHERE (OWNER, TABLE_NAME) NOT IN 

  3> (SELECT DISTINCT OWNER, TABLE_NAME FROM DBA_LOGSTDBY_UNSUPPORTED) 

  4> AND BAD_COLUMN = 'Y'; 

  The above query has 1040 tables in a particular schema. All the these have no index is not null primary / unique.

  
  Now according to the step 2 as below, we have an option to add a disabled RELY primary key constraint.

  Step 2 Add a disabled RELY primary key constraint.

  If your application provides the rows in a table are unique, you can create a primary key disabled RELY constraint on the table. This avoids the overhead of maintaining a primary key on the primary database.

  Can someone explain what this RELY constraint is disabled and how to function and help please?

  
  I have a few questions about the constraint to RELY.

  (1) change current plans of optimizer on primary for the execution price?

  (2) can help to boost the performance of SQL apply without creating index on the logical standby database?

  (3) it will change current plans of optimizer logical pending for the SQLs running?

  What are the options that I need to increase the performance and table scan complete engine AVOID SQL apply on the logic of the day before?

  Thanks a ton for reading my post.

  
  Kind regards

  In fact, I've implemented a key primary rely disabled on primary and unique index on the logic of the previous day.

• LOG_ARCHIVE_DEST_2 parameter error and cannot start the primary database

  Hello
  I was getting errors in my RMAN backup script. I took a glance on the database settings. Looks like I made a mistake when I was in the LOG_ARCHIVE_DEST_2 setting in the standby database. Instead of putting on the eve I put it in the name of the primary instance. I also noticed that the LOG_ARCHIVE_DEST_2 setting has been changed in the primary database where I put it first. I guess he's changed when I changed the sleep setting. I have two questions:
  
  (1) can the parameter LOG_ARCHIVE_DEST_2 be changes for the correct setting now that I set it wrong. The reason why I ask is because when I tried to change by using the following ALTER SYSTEM command I got an error saying something about conflicting attributes. I guess it's because the name of the primary instance has been upgraded with the DB_UNIQUE_NAME instead of the name of the standby instance. If I could change the LOG_ARCHIVE_DEST_2 setting to sleep first then maybe I can change the primary to the correct setting? Please provide markets.
  
  ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 ='SERVICE = < DB PRIMARY > ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = < PRIMARY_INSTANCE > '
  
  (2) the second question is you can start a database using a spfile? (I use ASM and Data Guard) I ask because while I was connected to the primary database I executed the following command:
  
  ALTER SYSTEM SET LOG_ARCHIVE_DEST_2 = 'SERVICE = < PRIMARY_INSTANCE > ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = < PRIMARY_INSTANCE >' scope = spfile;
  
  I then stop the database and try to start but it won't start because it says to conflicting attributes. I don't create a pfile from spfile file before you shut down the database. (I'm bad). How can I change the setting for the primary database to start over. (The PFILE file is different in ASM. There are sub + DATA but has only a single line indicating where is the location of the SPFILE) I need to run the following RMAN RESTORE CONTROLFILE FROM backup AUTOMATIC;
  
  Please help as it is a production environment that was supposed to be delivered only yesterday.
  
  Any help will be greatly appreciated!
  
  Thanks in advance.

• move the primary database files to another location

  Hi all
  
  I move the files of my primary database to another location on the same server, but on a different drive (from f: to G :) with rename comand but file name will be the same, after you have moved the files what step I need to perfom on standby DB will have on my database pending?)

  This doc is everything after you rename the primary file, I'm not rename all the files I need to just move file from one place to another without changing the file name.

  I hope you know how to move files from one place to the other on the primary database. It's not just copying the files from one disk to another and then to go to the top of your database.

  You rename your data files or copy it to another location, how the controlfile to know you have copied/renamed to a different location?

  I guess you 1 to ask the question of how to move files to a different location in primary education and then move on standby.

  Steps to follow:
  1 Hope you brought your primary database.
  2 copy the datafiels to one disk to another.
  3. attach the primary database.
  4 rename all data files that you moved to this control file would know the changes.
  SQL > alter rename file 'G:\oracle\user01.dbf' to 'F:\oracle\user01.dbf ';
  5. subsequently open the database.
  Refer this to move data files from one place to another http://www.orafaq.com/wiki/Move_datafile_to_different_location, http://www.adp-gmbh.ch/ora/admin/move_datafiles.html

  on autonomy in standby:
  1 cancel the MRP
  2. change the db_file_name_convert to point to «F:\»... »
  3. Mount the backup database
  4. start the MRP

  Hope that these steps are clear.

  All records of the primary database in the backup catalog are applied with success, until no 6 but not 7 would give me an error indicating that the required media recovery. Can someone help me?
  
  Thanks in advance...

  HI srp.

  As u mentioned above you are primary database server crashed.

  Now, you want to switch to mode ensures primary school.

  Use the following commands to go to primary school

  1 startup nomount
  2. change the mounting base pending;
  3. recover standby database managed disconnect from the session.
  4 recover managed standby database finish skip standby logfile;
  5 change the database for validation at the grade crossing;
  6. immediate cessation
  7. starting

  Otherwise, you need to activate the standby database using the command sequence

  SQL > recover managed database finish pending;
  SQL > alter database activate standby database;
  SQL > stop & start.

• Retrieve the primary database before database

  Hi all
  I'm trying to understand how to use databases of physical sleep in order to have a backup from a primary database.
  
  The first part is very clear. I guess I have a loan of the physics of the standby database and primary database archiving, but the second part is the problem.
  
  1. now, I guess my primary database went... not only a logical corruption but a physical disaster such an o fire something worse.
  How to recover the main site of the physical database ensures?
  
  2. just logical changes in the primary database. How to synchronize with the database on hold that he is one who has the right data?

  If you lose the database, then you normally would failover to the standby mode it becomes the main new.

  So you take a backup of the first news and use it to create a watch on the former primary server. When it is updated, you can then pass to the original configuration.

• An error occurred during the execution of the request for export: could not allocate space for object ' dbo. DS_Property_Member_Array'. 'IdxPropMbrArr04' to database 'EPMA' because the 'PRIMARY' filegroup is full.

Create disk space by deleting unnecessary files, removing objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on it to the existing files in the file group.

  No idea where I need to check the space I checked my essbase server and workspace and they both seem to have enough space for a normal deployment.

  It's a question on the SQL Server database with the allocation of space, searching the Internet for something like "Create disk space by deleting unnecessary files, removing objects in the filegroup" and you should get a lot of results.

  For example - the primary filegroup is full SQL Server 2008 - database to stack Exchange administrators

• How the records are selected in the database

  Hello

  How the records are selected in the database

  
  

  Thank you.

  Read articles on JDBC, here is what I understand...

  If I set LignesMax = 1 (in out select adapter DB) and I have 30 record in the table that satisfy the select query then what line is picked up? the first in the table or randomly any folder?

  The query returns the first line of the result set.  Not just a random line.  However, to get the rows to return in the result set in a specific order, you must include an order by clause, or the query will return rows in random order.

  And if I set LignesMax = 0 (unbounded, means any number registration) in this case if my select query satisfy 100 million documents so all million records will be picked up once, in one cycle?

  The answer to this depends on the size of the extraction of the query.  If the size of the extraction is > = 100 million, everything goes back in a single cycle of the DB.  If< 100="" million,="" then="" it="" will="" be="" divided="" into="" multiple="" trips="" to="" the="">

• How the portal is mapped in the schema of the database database?

  How the portal is mapped to the schema of the database selected in the user profile of portal to the database? It is my understanding that each user connects to the database as a 'Portal' that is configured by default in the dad under PlsqlDatabaseUsername. How the database schema selected in the portal user profile come into play?
  
  Thanks in advance for your help:
  Aimee

  Oracle Portal users are not defined in the database. They are defined as inputs in your LDAP server (Oracle Internet Directory) below the tree defined as a basis for research of the users in the Oracle Portal:

  Portal generator > Administration > global settings > tab: SSO/OID

  Therefore, there is no mapping between users defined in Oracle Internet Directory and the users defined in your database.

  To connect to the database, Oracle Portal uses the authentication of the Proxy (http://docs.oracle.com/cd/B28359_01/java.111/b31224/proxya.htm). Connections are made mainly by the user PORTAL_PUBLIC (who is often mentioned as part of the database schema in the user properties). The schema of database in the portal user profile defines the schema that is used to perform the procedures in the database of Portal metadata repository. Theoretically, you can use a different schema than Oracle Portal, but I have not seen all cases where this has been helpful.

  Thank you
